Zeolite Concentrator Rotor(ZCR)

Comprehensive overview

ZCR (Zeolite Concentrator Rotor) is a rotating adsorption device prepared by attaching molecular sieve adsorbent material to a honeycomb porous carrier.

Working Principle

The zeolite rotor utilizes zeolite molecular sieves as the adsorption material, which adsorbs and filters organics larger than air molecules, while air passes through directly. The zeolite rotor with a honeycomb structure is installed in a housing separated into three zones of adsorption, regeneration, and cooling, and is driven by a speed-regulated motor to rotate slowly at a speed of 1 to 6 revolutions per hour. Polluted air containing VOCs is sent to the adsorption area of the zeolite rotor by a blower, and when the polluted air passes through the honeycomb channel of the zeolite rotor, the VOCs contained in it are adsorbed by the adsorbent, and the air is purified. With the adsorption rotor rotary, close to the adsorption of saturation state of the adsorption rotor into the regeneration area, in contact with the high temperature between 180 ℃ -220 ℃ desorption of regeneration air, VOCs are desorbed into the regeneration of air, zeolite rotor regeneration. After regeneration, the zeolite rotor is cooled down in the cooling zone and returned to the adsorption zone to complete the cycle of adsorption/desorption/cooling.

Typical Processes

The center of gravity of the rotor concentrator is a large rotor made of zeolite molecular sieve, which works cyclically in the adsorption zone, desorption (regeneration) zone and cooling zone. The exhaust gas passes through the adsorption zone when most of the VOC is adsorbed in the molecular sieve, the purified exhaust gas is discharged, and part of the exhaust gas passes through the cooling zone heated up to 120 degrees Celsius, while the cooling zone is cooled at the same time. The gases passing through the cooling zone are further heated to 200 degrees Celsius and pass through the desorption (regeneration) zone to desorb the VOCs adsorbed on the molecular sieve.

Main features

• High adsorption and desorption efficiency reduces the cost of back-end treatment equipment;
• Zeolite rotor adsorption of VOCs produces a very low pressure drop, which can greatly reduce the power energy consumption;
• Concentration factor reaches 5-20 times, so that the original large air volume, low concentration of VOCs exhaust gas, converted into low air volume, high concentration of exhaust gas, greatly reducing the specifications of the post-treatment equipment, low operating costs;
• The overall system is pre-assembled and modularized to meet small space requirements and provide continuous and unmanned operation;
• System automation control, single button start, simple operation, and can be equipped with human-machine interface to monitor important operating data. The exhaust gas after concentration by rotor can meet the emission standard.
